What country leads renewable energy?

It was reported that 13 of the 14 warmest years on record have all occurred since 2000. Scientists consider that such change of global climate is primarily a problem of too much carbon dioxide in the atmosphere. To stop climate change, many countries have been trying to generate their electricity from renewable resources as much as possible by using sunlight, wind, and water. By increasing the use of renewable resources and reducing the use of fossil fuels (oil, coal, and natural gas), we will be able to reduce a lot of carbon dioxide in the atmosphere.
